I was once called on the carpet for "not having an appropriate sense of urgency" while calmly diagnosing and repairing (quickly, I might add) a server outage.

My response was that in an emergency, you don't want the ambulance crew and the fire crew to be as freaked out as you are. You want their handling of the situation to be calm and smooth.

Can you imagine the fire truck showing up and the first guy off the truck standing in front of your burning house screaming, "Holy crap, that house is ON FIRE."?

No, you want that guy to move the freaked out people off to the side and take control of the situation and put the damned fire out.
